Precise measurement of weight refers to repeated measurements taken for the weight of an object, in which all the results are very close to one another. They could all be wrong by the same value.

For example, suppose you have a pair of kitchen scales which show 100 grams when there is nothing on them. Suppose you weigh a single bag of flour several times. The results may be 601g, 600g, 601g, 602g, 599g. The results are all within 1 gram of 600 g indicating a high degree of precision. But a totally useless result since the result is not accurate: the true weight is 500 grams, and the zero error has displaced each measurement.

Actually, the weights should be given in Newtons (or millinewtons), not grams, which is a unit for measuring mass, but for the sake of simplicity I have indulged myself.

No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).

The unit of measurement best suited for weighing a pea would be grams, as it is a smaller, more precise unit for measuring the weight of small objects like peas.

An automatically measurement has a higher precision than a manually measurement.

19.2cm is more precise

The precision of a measurement can be determined by looking at the number of decimal places in the measurement. The more decimal places, the more precise the measurement. Additionally, if a measuring tool is capable of measuring smaller increments, it can provide a more precise measurement.
